Open Stack

Hi again,

I managed to install the kmod rpms in the overcloud-full.qcow2 image:

|sudo yum -y install 
https:||//www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm|
|sudo yum -y install --downloadonly --downloaddir=. kmod-mptsas|
|sudo yum -y install --downloadonly --downloaddir=. kmod-megaraid_sas|
|
|
|The deployment works fine, but as soon as the node reboots it is just 
stuck with a blinking cursor after loading the kernel.|
|
|
|Do I have to add something else to the overcloud-full image as well?
|
